Wando is a very tough opponent with high quality players in Brandon Burkholder, Erik Clark and a fan base as hell bent on soccer as the IRMO fans are. On top of that, I don't remember a bad match-up between these to schools in over 10 years. It is always a game to see.
Having said that, I'm betting IRMO will get through there will be an IRMO vs Northwestern Final. Could be wrong, but I doubt it.
